ABSTRACT:
A dual mode battery charging device for charging a plurality of batteries includes a battery charging section for charging the batteries, and a charging control section for changing the switching period of a charging signal in the battery charging section in accordance with the number of batteries to be charged and outputs a control signal to the battery charging section which determines whether the charging section operates in a standard charging mode or a quick charging mode. In accordance with the number of batteries mounted, only one battery can be quickly charged or two batteries can be simultaneously charged at a normal speed. Therefore, the capacity of a battery and its available time increase.
